Status Monitoring
Status Monitoring
This section provides a summary of status monitoring and reporting for a
Gecko 8900 Series system. It also summarizes what status items are
reported and how to enable/disable reporting of each item. There are a
number of ways to monitor status of modules, power supplies, fans and
other status items depending on the method of monitoring being used.
8900 Frame status will report the following items:
• Power supply health,
• Status of fans in the frame front cover,
• Temperature,
• Module health, and
• Frame bus status.
Module health status will report the following items:
• Internal module state (and state of submodule or options enabled)
including configuration errors (warning), internal faults, and normal
operation (Pass).
• Signal input states including valid/present (pass), not present or
invalid (warning), not monitored, and not available (no signal inputs).
• Reference input states including locked/valid (pass), not
locked/invalid (warning), and not monitored.
• Signal output states with reporting functionality (reference output).
LEDs
LEDs on modules in the frame and on the front of the 8900TF/TFN frames
indicate status of the frame and the installed power supplies, fans in the
front covers, and modules. (The 8900TX-V/A frames have no LED indica-
tors on the front cover.)
When a red FAULT LED is lit on a frame front cover, the fault will also be
reported on the 8900NET or Frame Monitor module. The LEDs on the front
of these modules can then be read to determine the following fault condi-
tions:
• Power Supply 1 and 2 health,
• Fan rotation status,
• Frame over-temperature condition,
• Frame Bus fault (8900NET only), and
• Module health bus.
